Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed March 18, 1907. Serial No. 362,992.

To all whom it may concern:

Be it known that I, MICHAEL J. OORCORAN, a citizen of the United States,residing at York, in the county of York and State of Pennsylvania, haveinvented certain new and useful Improvements in Whililetree- Hooks; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in whiffle tree hooks.

The object of the invention is to provide a hook of this character bymeans of which a trace may be readily engaged with and secured to aWhittle tree and which may be quickly and easily operated to release atrace therefrom.

With the foregoing and other objects in view which will appear as thenature of the invention is better understood, the invention consists incertain novel features of construct-ion, combination and arrangement ofparts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure l is a perspective view of one endof a whifle tree showing the hook applied thereto and in closed positionto secure a trace thereon; Fig. 2 is a similar view showing the hookopen to permit the trace to be disengaged from the end of the whifi'letree; Fig. 3 is a longitudinal sectional view of the end of the whiflletree and hook showing a sectional View of a trace engaged therewith.

Referring more particularly to the drawings, l de-- notes the end of awhiifle tree, to the upper side of which is secured my improved hooks 2,which consists of a longitudinally-disposed bar 3 on the inner end ofwhich is an integral downwardly-projecting right-angular-ly formed lug 4on the lower end of which is formed a right-angularlylongitudinally-extending securing plate or bar 5, said bar 5 projectingin the opposite direction from the upper bar 3.

In the plate or fastening bar 5 is formed two or more screw or boltholes 6 through which and into the whiffle tree are adapted to be passedfastening screws or bolts 7 by means of which the hook is secured to thewhifle tree.

On the outer end of the bar 3 is arranged a retaining arm 8, said armbeing provided on its upper end with an enlarged portion which forms ahead and is adapted to engage the outer end of the bar 3, as shown.

The arm S is pivotally connected to the end of the bar 3 by means ofthe-pivot bolt or screw 9 which is passed through a hole in the head ofthe arm and is adapted to be screwed into engagement with a threadedsocket or recess I0 formed in the end of the bar 3. By thus pivotallyconnecting the arm S with the end of bar 3 and the upper side of thewhifHe tree and securely holding the trace from disengagement therefrom.

In order that the arm 8 may be held in an operative or inoperativeposition, I provide a flat spring l2 which is secured to the upper sideof the bar 3 by screws or other fastening device. The outer end of thespring l2 projects beyond the end of the bar 3 and is adapted to engagethe upper square surface of the head of the arm 8 when the latter is inan operative position and to engage one side or the other of the head ofthe arm when the latter is turned upwardly in either direction to aninoperative position, as shown in Fig. 2 of the drawing. The engagementof the spring with the head of the arm 8 will hold the same againstcasual movement when turned to either an operative or inoperativeposition and at the saine time will permit the arm to be readily turnedfrom one position to the other. y

A while tree hook constructed as herein shown and described will besimple, strong, durable and inexpensive in construction, efficient andreliable in operation and well adapted for the purposes for which it isdesigned.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood Without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention, as defined by theappended claims.

Having thus described my invention, what I claim as new is,-

1. A whiletree-hook comprising a right-angulariy shaped bar, means tosecure the same to a Whiliietree, a trace retaining arm pivotallymounted on the outer end of said bar, a fiat spring, and means on saidarm adapted to be engaged by said spring to hold the arm in an open orclosed position. substantially as described.

2. A whiiiletree-hook comprising a right-anguiarly shaped bar, means tosecure the same to a whiHle-tree, a trace retainingarm pivotally mountedon the outer end of said bar, a spring, and a squared head on the upperend of said arm, the right-angularly disposed sides of which are adaptedto be engaged by said spring to hold said arm in an operative andinoperative position, substantially as described.

A whiflle tree hook comprising a longitudinally-disposed bar havingatone end a rightangularly downwardly-projeeting lug, an integrally formedfastening plate on the lower end of said lug, said plate projecting inthe opposite direction to said bar, means to secure said plate to aWhiflle tree, a trace retaining arm arranged on the outer end of saidbar, a pivot screw passed through the upper end of said arm and adaptedto be screwed into engagement with a threaded socket in the end of saidbar whereby said nrln is connected to the bnr to turn laterally thereonyand a flat spring secured to the upper sides of the bar-and projectingbeyond the ends of the same to engage said arm and hold the same in anopen or closed position, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
